2. Instrumentation
In this section, we will only discuss spectrophotometers that can be used to obtain spectra and measure absorbance, which excludes simple colorimeters or photometers with a fixed wavelength.
2.1 Component organization
Devices can be classified into two categories:
single-beam devices, which are further subdivided into devices with direct optical mounting or inverted optical mounting;
dual-beam devices with direct optical mounting.
The choice of device will depend on the problems to be solved: it can be said that dual-beam devices are the most effective in terms of various analysis possibilities and metrological characteristics; they are generally...
